# vSphere Topology Visualization

This plugin uses the data from the _VMware ESX via vSphere_ special agent to create a topology of the vSphere environment.\
The topology contains the vCenter -> Data center(s) -> Clutser(s) -> VMs -> Datastore(s)\
It creates the topology on the fly with each check cycle. The plugin will also work in host only mode.

### Acknowledgements
ThX to [adadietrich](https://forum.checkmk.com/u/adadietrich/summary) for the idea and for being my beta tester

### Known issues

- The topology is only available on the site where the vCenter servier is monitored. There is no sync for topology files from reemote sites to the central site. As a workaround you could create a rsync job that copys the topology data to the main site.
- There is no direct access (link) to a specific topology, if use other topologies as well, you might need to select the right topology for display  via `Compare history` -> `Reference` -> `Compare to` on the topology screen.
